SPECIFICATION forming part of Letters Patent No. 323,857, dated August 4, 1885.

Application filed September' 26, i884. (No model.)

To all whom it may concern:

Be it known that we, RICHARD GUR'ris and WILLIAM HENRY RHODES, subjects of the Queen of Great Britain, residing at Manches ter, in the county of Lancaster, England, have invented a new and useful Improvement in Roving-Frames, Sie., (for which we have obtained a patent in Great Britain, No. L1,560, bearing. date November 6, 1880,) of which the following is a specification.

Our invention relates to slubbing, intermediate, and roving or jack frames, (also called speedei's 5) and the object of our invention is to provide improved mechanism for imparting a gradually-decreasing speed to the bobbins, so that the bobbins shall always draw the slubbing or roving from -the front rollers at a uniform speed, notwithstanding the increase of the diameter of the yarn on the bobbins as they become filled.

In performing our invention we dispense with the ordinary jack-in-the-box 7 or differential motion usually employed to communicate motion from the driven or lower cone-drum to the bobbins and substitute the improved mechanism hereinafter described and illustrated in the accompanying drawings, in which- Figure l is an elevation, and Fig. 2 is an end view, of part of a roving-frame or Speeder, to which ourl improvements are applied. Fig. la is an end view, and Fig. 2L is an elevation, of

chet to shift the strap on the conc-pulleys, and the shaft with its skew-gears to rotate the bobbins, both figures showing parts broken away. Fig. 3 is a longitudinal sectional elevation of our improved mechanism, and Figs. 4 and 5 show either side of the disk j with the wheels that revolve therewith. Fig. 5 also shows a section ofthe wheel n,

a is the ordinary driving-shaft, and b is the wheel fixed on the shaft, which imparts motion to the spindles, as usual. c is the twistwheel, also fixed on the driving-shaft, which drives the top cone-shaft, c', by the wheels c2 and ci. Cn the shaft c is a Wheel, c4,vthat drives the drawing-rollers by a wheel, c5, fixed on the front roller-shaft. The top cone drives the lower cone at a decreasing speed by a strap, d. The roving-frame is started with the strap d at the large end of the top cone, and so Patented in England November 6, 1880, No. 4,560.

drives the lower cone at a graduallydecreasing speed as strap cl is t1 aversed from the larger to the smaller diameter of the top cone by a strap-guide, d', actuated by a rack, s, and 55 ratchet-wheel tin the ordinary manner. When the bobbins are filled with roving or yarn, the strap d will have been moved to the small end of the top cone. Before restarting the rovingframe the strap d is moved back again to the 6o large end of the top cone. To effect this the bottom cone is raised by a worm, and wheel w actuated by thehand-wheel y, and rack s is caused to traverse after releasing the ratchet t by turning the hand-wheel u on the shaft u. The lower cone transmits motion by the Wheels d2 cl3 and d4 d5 to the wheel c, which forms part of our improved mechanism for transmitting motion to the bobbins. The Wheel c is fixed to the sleeve f, which is loose on and is turned 7o in the same direction as the driving-shaft a. On the other end of the sleeve f is fixed the wheel g, which gears into and rotates a double carrier-wheel,.h la', which `turns on a stud, i, fixed :to the disk j, which is fixed on the driving-shaft a. One part of the carrier-wheel h gears into a wheel, 7c, xed on a short shaft, l, which turns in a bearing formed in a boss on the disk j. At the other end of this shaft Zis fixed the wheel m, which gears into an inter- 8o nally-toothed wheel, n, which is loose on the drivin g-shaft a. The wheel a has a long boss,

on which is fixed the Wheel o, that transmits motion through the carrier-wheel p to the wheel q, fixed on the bobbin-shaft r. The 8 5 wheel q also gears into and drives a similar sized wheel, q', on the front bobbin-shaft, r'. On the bobbinsh afts r r are the skew 7 bevelwheels r2 r3, which rotate the bobbins in the usual manner.

We make the wheel o with about one-tenth more teeth than the Vwheel b, to cause the first lap on the bobbins to be Wound at the desired speed. The wheels c and g turn in the same direction as the drivin g-shaft a, but at a slower 95 speed. The wheel g causes the double carrierwheel h h to rotate at the same time that it revolves round the shaft a. The smaller Wheel of the double carrier-Wheel h h rotates the wheel k and the wheel m as they revolve round 10o the shaft a, and the Wheel m gears into and turns the wheel n, which transmits motion through the u'heel o, earrierp, and wheel q to the bobbin-shai't r.

As the shaft a is driven at a uniform speed, and as the wheel 'f/ is Caused to rotate in the same direction, hut at a- `graduallydecreasing speed, the wheel m will be caused to make ay slight and inereasingl backward rotary movement as it revolves round the shaftl a, (in the direction indicated by the arrows on Figs. 4t and 5,) thus eommunieatin g a deereasin g speed to the 1nternally-toothed wheel n, and by the wheels 0,27, and q to the bobbin-shaft 1', thus causing` the bobbins t0 turn at the desired speed to draw the yarn at a uniform speed from the front rollers.

What We claim as our invention, and desire to secure by Letters Patent ot' the United States, is-

The combination, with the drivingshaft a.,

and the diskj, fixedlyseeured thereon, and provided with a sind, and shai't Lof' the wheel e, looselbr mounted on the driveshat't u, a wheel,

g, connected therewith, means for rotating said wheel e and its Wheel g, the double earrier-u'heel h l1. on stud i, the wheels 7c m at.

opposite ends of the shaft l, the Wheel g, operating,r the wheel hi, and tne wheel h', operating,` the wheel 7., the internally-toothed wheel n, mounted loosely on the driving-shaft a, and the wheel o, eonneeted with the u'heel n, substantially as set forth.

The oregoing specification of our improvement in meeh ani sm for imparting; a. decreasing speed to the bobbins of slubbing, intermediate, and roving' or jack frames signed by us this 21st day of August, 1884.
